The effect of ethanol (ETOH) exposure on the IGF type II receptor concentration was examined in 18 and 20 day fetal rat tissues. Pregnant dams were fed an ETOH (36% of calories derived from ETOH; 6.6% v/v) liquid diet. Control fetuses were offspring of dams either pair-fed a control liquid diet or ad libitum-fed a standard pelleted lab chow. Fetal brain, heart, kidney, liver, lung and skeletal muscle were removed and whole homogenates from individual animals were analyzed. Results of immunoquantification of IGF type II receptors in whole tissue homogenates show that there is a trend towards increased receptor concentration between 18 and 20 days in all tissue and this trend is significant for lung, liver and muscle. There were no significant differences in receptor concentration between treatment groups. These studies suggest that during the later stages of fetal development, there is an increase in total IGF type II receptors and this increase is undisturbed by ETOH exposure.

D000431 Ethanol A clear, colorless liquid rapidly absorbed from the gastrointestinal tract and distributed throughout the body. It has bactericidal activity and is used often as a topical disinfectant.

D017527 Receptor, IGF Type 2 A receptor that is specific for IGF-II and mannose-6-phosphate. The receptor is a 250-kDa single chain polypeptide which is unrelated in structure to the type 1 IGF receptor (RECEPTOR, IGF TYPE 1) and does not have a tyrosine kinase domain.
